Reproducibility Variable Result LLM Response
Research Type Theoretical We study Phragm en s methods from an axiomatic point of view, focussing on justified representation and related properties that have recently been introduced by Aziz et al. (2015a) and S anchez-Fern andez et al. (2017). We show that the sequential variant satisfies proportional justified representation, making it the first known polynomial-time computable method with this property. Moreover, we show that the optimization variants satisfy perfect representation. We also analyze the computational complexity of Phragm en s methods and provide mixed-integer programming based algorithms for computing them.

Open Source Code No The paper does not provide any statement or link indicating that source code for the described methodology is publicly available.
Open Datasets No The paper is theoretical and does not use datasets for empirical evaluation. The examples provided are illustrative, not empirical data.
Dataset Splits No The paper does not involve empirical experiments with datasets, and therefore no specific dataset split information (train/validation/test) is provided.
Hardware Specification No The paper is theoretical and does not describe experiments that would require specific hardware specifications.
Software Dependencies No The paper mentions 'mixed-integer linear and quadratic programming' as the basis for algorithms but does not specify any software names with version numbers for dependencies.
Experiment Setup No The paper is theoretical and describes algorithms and properties but does not detail an experimental setup, including specific hyperparameters or system-level training settings.
